About this 0.69ct natural heart diamond

This 0.69ct natural heart sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3545970840. Listed at 4 retailers as of October 30, 2026, with prices from £613 to £1,923, a £1,310 spread on the same certified stone. NZ Jewellers lists it at £1,923. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
